I recently completed a project using FParsec (http://bitbucket.org/fparsec/main http://bitbucket.org/fparsec/main), which is a parser combinator (http://en.wikipedia.org/wiki/Parser_combinator http://en.wikipedia.org/wiki/Parser_combinator) library based on Haskell's Parsec (http://www.haskell.org/haskellwiki/Parsec http://www.haskell.org/haskellwiki/Parsec).
